often when encounter error a method named '/member/insert' lready defined, means creating new mongo.collection('member') more 1 time.

perhaps doing in array.foreach function (which calls multiple times if array has more 1 element).

from error logs looks caused fn in _.each(array,fn) @ server\boot.js.
